Create React App 2.0

#What’s New -More styling options: you can use Sass and CSS Modules out of the box. -We updated to Babel 7, including support for the React fragment syntax and many bugfixes. -We updated to webpack 4, which automatically splits JS bundles more intelligently. -We updated to Jest 23, which includes an interactive mode for reviewing snapshots. -You can use Apollo, Relay Modern, MDX, and other third-party Babel Macros transforms. -You can now import an SVG as a React component, and use it in JSX. -You can try the experimental Yarn Plug’n’Play mode that removes node_modules. -You can now plug your own proxy implementation in development to match your backend API. -You can now use packages written for latest Node versions without breaking the build. -You can now optionally get a smaller CSS bundle if you only plan to target modern browsers. -Service workers are now opt-in and are built using Google’s Workbox.
